networking - Jenkins server is not accessible by host name (ip address)

Question

I setup jenkins on my Mac OS X with homebrew and it works just fine via http://localhost:8080 or http://127.0.0.1:8080 I couldn't access jenkins instance via hostname/ipaddress:

 1. http://myjenkinshost.local:8080
 2. http://192.168.0.100:8080

Both links are not accessible even from local computer (jenkins host itself). Same time commands ping 192.168.0.100 and ping myjenkinshost.local work just fine.

Answer 1

It turned out that launch agent was configured to listen only 127.0.0.1 (or localhost). To fixed that edit jenkins agent's plist:

nano /Users/admin/Library/LaunchAgents/homebrew.mxcl.jenkins.plist

and modify httpListenAddress to 0.0.0.0 instead of 127.0.0.1
